Hi Guys, it is very common to place an entry order with a related stop and limit order. Can this be done in QuantConnect?

Yes, it can be done.
Please checkout the docs under the Trading and Orders section.
We support many different order types. In live trading some of these order types may be simulated depending on your brokerage (for more information on this see Live Trading):
// Various order types: // Fill a market order immediately (before moving to next line of code) var newTicket = MarketOrder("IBM", 100); // Place a long limit order with limit price less than current price var newTicket = LimitOrder("IBM", 100, lastClose * .999m); // Closing out a short position; long stop above the last close price var stopPrice = close * 1.0025m; var newTicket = StopMarketOrder("IBM", 100, stopPrice); // Closing out a long position on market drop var stopPrice = close * .9975m; var newTicket = StopMarketOrder("IBM", -100, stopPrice); // Limit order trigger on reaching the stop price var newTicket = StopLimitOrder("IBM", 100, stopPrice, limitPrice); // Market on Open/Close: var newTicket = MarketOnCloseOrder("IBM", 100); var newTicket = MarketOnOpenOrder("IBM", 100);There are working QuantConnect University examples where the limit/stop orders are updated if not filled after a given period.

Hi Alexandre, thank you very much, but I am not sure you answered my question:-). Imagine my algorithm has discovered an opportunity to enter the market "now". I would like to stay in the market until I have either lost 2% or I have "won" 10%. This is a fairly common scenario.
I would then like to do something like this:
currentPrice=... whatever;
stopPrice=currentPrice*0.98;
takeProfitPrice=currentPrice*1.10;
var orders {
entryOrder:new MarketOrder("IBM",1000),
relatedOrders {
stopLossOrder:new StopMarketOrder("IBM",-1000,stopPrice),
takeProfitOrder:new LimitOrder("IBM",-1000,limitPrice)
}
}
PlaceOrders(orders);
The idea is that:
a) The stop and Limit orders are only created if the market order was successfully executed and resulted in a position.
b) The stop and Limit orders are explicitly linked to the position created.
c) If later I hit the stop order, the limit order is cancled, and visa versa, so I don't end up suddenly being short, if the limit price and then the top price are hit in close succession..
I know that I can probably code this as part of the algorithm, but most brokers support these type of three way orders out of the box, and it is quite nice to have the stopLoss and takeProfit orders rest at the broker (should the QuantConnect server be down).

Currently, we need to manage the two exit orders (cancel one when the other is filled). We can easily do that in the OnOrderEvent event handler.
I wrote a simple algorithm where I propose a solution to a three way order. In this solution, we use the Tag member of the OrderTicket class to save the entry order id number:
// In OnData method: var quantity = 100; var currentPrice = data[_symbol].Price; var stopPrice = currentPrice * 0.98m; var takeProfitPrice = currentPrice * 1.10m; var entryOrder = MarketOrder(_symbol, quantity); // Using the Entry order Id number to relate orders _entryOrderId = entryOrder.OrderId; StopMarketOrder(_symbol, -quantity, stopPrice, _entryOrderId.ToString()); LimitOrder(_symbol, -quantity, takeProfitPrice, _entryOrderId.ToString());Once one of the exit orders are filled, we look for the orders that were tagged with that number and cancel the order that is still open:
// In OnOrderEvent method: // Get orders that we tagged with the entry order number var tickets = Transactions .GetOrderTickets(x => x.Tag == _entryOrderId.ToString()); foreach (var ticket in tickets) { // Cancel the open orders (should be just one) if (ticket.Status.IsOpen()) { ticket.Cancel(); } }The stop loss and take profit orders rest on the brokerage. For that reason, if the brokerage does not support one of our order types, the algorithm will not place the order and warns the user.

Would it be possible to get this example in Python please?
Halldor Andersen
Hi Matthew.
I've attached a backtest where I demonstrate how to set Take-Profit and Stop-Loss in Python. Also, check out this documentation section on Tracking and Managing Orders for further information.
Jacob Barbee
Doesn't this only allow for one open position at a time? Say you have multiple open orders with their paired exit orders. How would you cancel the correct order after the take profit or stop loss is hit?
Varad Kabade
Hi Jacob Barbee,
We can extend the above implementation for multiple open orders by using a dictionary to store the order tickets by the order ID. Note that Lean does not allow multiple open positions. If you need further assistance regarding the same, please open a new thread.
Best,
Varad Kabade
